Zooni (Kajol), a blind Kashmiri girl, meets Rehan Qadri (Aamir Khan
), a local tour guide and an incorrigible flirt, who goes from city to city exploring their architecture as well as the women. Her friends warn her against this good-for-nothing roadside Romeo, but she chooses to ignore them. She believes this is her time to discover life, and love.
Rehan is fascinated by Zooni. He wants her to see life as it should be seen, in its many colors—and as he promises her, the time spent with him will be the most precious in all her life. Zooni sees Delhi, life and love like she never has before, because of Rehan.
What Zooni doesn’t know is that Rehan has another side of his life that he has kept from her—something that can not only change her life, but can also destroy it.
